Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990194, here are decompositions:

13 + 990181 = 990194
31 + 990163 = 990194
43 + 990151 = 990194
151 + 990043 = 990194
157 + 990037 = 990194
181 + 990013 = 990194
193 + 990001 = 990194
223 + 989971 = 990194

Showing the first eight; more decompositions exist.
